ings 23. These bearings are carried on Arods 24 which extend throughsleeves 25 on brackets 26, this constructionproviding for adjustment onthe shafts 22 so as to overcome any slack in the chains.

In the particular machine illustrated, the sheet supports operate tosupport the sheets on the sides only, thereby avoiding as far aspossible contact between the sheets and the sheet supports. With aconstruction such as described in which the sheet supports operate tocarry the sheets on the sides only, there is liability that the sheetsbeing unsupported at -theircenters will sag. The ysupports will,therefore, in the best constructions be so constructed as to preventthis sagging. While this may be done in various ways, it may beeifectively accomplished by so constructing the supports as to V'bendthe sheets out of line at the sides, this bending of thesheets at thesides serving to stiften them. In the particular constructionillustrated, the Abending of the sheets is effected by concaving thebars slightly, as clearly illustrated in Fig. 3, 'so that when the'sheets are deposited thereon they .will be bent up at their sides. Thesheetv receiver or receivers, if more than one be employed, will beintermittently Amoved from the sheet receiving to the sheet deliveringposition. The means by which this intermittent movement is accomplishedmay be of any suitable character. In the particular'constructionillustrated, the shafts -20 which carry thev upper sprockets areprovided with miter gears 27 in mesh with slmillar .ears 28 on a shaft29 suitably sup orted in the frame. The shaft 29 is provided with i agear 30 which is one of a train of gears 4o indicated at 31, which trainmay be operated from a ratchet wheel 32 supported on'a stud 33 extendingfrom the frame. This ratchet wheel may be operated by any suitable pawlmechanism, not illustrated, construction of this character being wellunderstood in the art. In thebest constructions, however, this movementwill be such as to give the sprockets a quarter turn so that the sheetsupports on the oppositely disposed to Vcarriers will be brought intosheet receiving position, thus avoiding any movement of the sheetsupports with respect to the sheets after the sheets have been placedthereupon. While the sheets might be removed from the sheet receivers invarious ways, in the best constructions including the invention, pile-delivery mechanism will be employed. This pile delivering mechanism maybe variously constructed but in the particular machine shown it includesa conveyer consisting of a series of chains 34 which are supported bysprockets 35, 36, these sprockets being supported on shafts 37, 38. Theconveyer chains, if desired., may be provided with spacing projections,indicated at 39. The

menace between the inner ends of the sheet receivers, as is clearlyshown in Fig. 1, and, further, will be such a distance from the revceiving position of the receivers, that as the receiver carriers aregiven the quarter turn referred to, the ends of the sheet supports willpass the sides of the conveyer, thus de* positing the pile of sheetsthereon. It will be observed that at the-time the receiversare movingfrom receiving to delivering position the movement is a parallel one, sothat the sheets are deposited on the conveyer without displacing thesheets.

If desired, supports, as 40, may be provided on each side of theconveyer, which supports will when employed, be so arranged as to bearonly on the margins of the sheets, thus preventing the sheets frombending downward and at the saineA time not smudging the sheets. Thesesupports may be madeof polished steel bars. In the particularconstruction illustrated, they are carried by brackets 41 supported oncross rods 42. The conveyer chains, to prevent sagging, may be providedat suitable distances apart with rolls 43 which run on supporting tracks44 carried on the cross rods 42 before referred to.

The conveyer, when it is employed, may be operated in any suitablemanner. In the construction illustrated, the shaft 38 is a driven shaftand is given a step by step vmovement by a ratchet wheel 45 and a pawl4G, this pawl being worked through connections 47 of the usual type froma cam or eccentric on the shaft 2. v

To prevent overthrow of the sheets, as they are delivered by thedelivering cylinder, there may be employed, if desired, sheet stops 48so located that the forward edge of the sheet will strike themas theyare released by the grippers 5, the sheets being thus caused to settleevenly on the sheet receivers. 'f Y Changes and variations may he madein the constructions by which the invention is carried into effect. Theinvention is not,

therefore, to be limited to the specic construction herein described andillustrated in the accompanying drawings.
